Commercial loan from 1 Lender, on 2+ properties, totaling 5+ units?

Do traditional lenders ever lend on more than one property and draft it as a single commercial loan on both properties when they total 5+ units?

If I can detach my partner from direct financial "proof"/liability, then that will help improve our ability for financing. I am just unsure if this is ever done.

We have two duplexes, and one fourplex. All of them are seller financed by the same previous owner, and if we can get a single lender to refinance with, that will greatly simplify everything.
